retrograde cystoscopy, a technique for radiographically examining the bladder in which a catheter is inserted through the urethra into the bladder, allowing the urine present in the bladder to pass through the catheter. A radiopaque medium is introduced, filling the bladder, and the contour of the bladder is observed, using serial x-ray films or fluoroscopy. Also called cystoscopic urography. See also cystogram, retrograde pyelography.
